海洋工程船舶节能推进器研究

Study on Saving-Energy Propeller of Sea-Going Engineering Ship

本文应用螺旋桨升力线理论,在浆后设计了一个固定叶轮装置,以回收桨后尾流旋转能量,提高推进效率。利用本文方法编制了计算程序,并与试验比较,两者吻合较为满意。试验表明,实船推进效率可提高约11.0%。

The paper designs saving-energy stators installed behind the propeller, according to some screw lifting theory. The stators can save rotational energy in slipstream and improve efficiency. The results predicted by the present method are compared with experiment date. The agreements are setisfactory. The stators can save eleven percent energy.
